摘要：

A flow control device for connection between a shower head and its supply pipe. The device consists of a fitting with one end attachable to the supply pipe and the other end attachable to the shower head. The fitting has a transversely slidable cylindrical valve element projecting on opposite sides of the fitting and provided with enlarged push buttons on its ends. The valve element has a peripheral groove which can be adjusted as to position in the bore of the fitting to give a desired rate of flow, or which can be moved away from the main bore to cause the valve element to shut off the flow, without requiring operation of the associated hot and cold water supply faucets. An air inlet passage is provided at the outlet side of the fitting to allow air to be aspirated into the water stream by venturi action, enabling the air to be mixed with the water in the spray head to thereby provide a regulated amount of aerated water in the shower head discharge.
